Bringing a smartphone to the other world was actually an anime?

This reminds me of a very interesting anime,"Travelling to the Other World with a Smart Phone." This work told the story of the protagonist, Xiao Ming (male protagonist), who used his smartphone and various online applications to embark on a thrilling adventure after crossing into the other world. Not only did this work have an exciting plot and cute characters, but it also involved many elements related to modern technology, making people look forward to the future of the Otherworld. If you are interested in this anime, I suggest you go and take a look. I believe you will gain something.
